There are few car companies I can think of that embrace multiple versions of their brand names.
The only other ones that come close, I think, are Volkswagen and BMW. Volkswagen is commonly referred to as VW, of course, even in the company’s marketing. You can call BMW Bavarian Motor Works (or the German version which I won’t try to spell or pronounce), but that isn’t nearly as common in their marketing.
Sure, you can refer to a Cadillac as a “Caddy” or a Jaguar as a “Jag” or a GMC truck as a General Motors Corporation truck or a Mercedes-Benz as either a Mercedes or a Benz. But those alternate names aren’t really used in the marketing for those brands (and certainly are not used as their top-level domains for their sites).
But then there’s Chevrolet, which gives us nuggets like this:
Chevrolet is often referred to as simply Chevy. Chevy or Chevrolet. They’re interchangable.
What’s interesting is that Chevrolet actually promotes Chevy.com as the place to get more car information:
It’s not a bad strategy. In our common American culture, Chevy is practically a household name. Why not take advantage of that to make it easier for web surfers to type your address?
I once asked a PR person at an auto show about this. Did they have a preference of one over the other? She said, no, they embrace both Chevy and Chevrolet as their brand.
So what happens when you go to Chevy.com?
Branding is important, but I applaud Chevrolet (or Chevy) for embracing its dual personalities.
